The Niles Audio SMS-10C Rack-Mount Speaker Distribution / Impedance Matching System with Cover is a great way to send audio out to 10 pairs of speakers (20 speakers total) from one receiver or amplifier. The autoformer matching system maintains a nominal 8 ohm load on the receiver or amplifier and prevents the loss of power associated with conventional resistive protection methods. Each of the up to 10 pairs of speakers can have a nominal impedance anywhere between 4 and 16 ohms. Programming pins are included on each autoformer, making installation easy and specific to the number of speakers being used. The Niles Audio SMS-10C was designed for use with a standard 19" wide equipment rack and will only take up 2 rack spaces. This version features a sealed metal cover that allows all the wiring to be contained within the cover. Eight electrical box type knockouts (3/4" in diameter) are provided for installations requiring a conduit.
